A "set-top box" is a cable, satellite, Internet Protocol or other device whose primary function is to receive television signals from a specific source and deliver
them to a consumer display and/or recording device, such as a television or DVR.
ENERGY STAR certified set-top boxes are on average 40 percent more efficient than conventional models.
If all set-top boxes in the U.S. met ENERGY STAR requirements, consumer energy cost savings would grow to about $1 billion each year, reducing greenhouse gas emissions equivalent to those from about 2 million cars.
Current Specification Effective Date: Version 3.0: September 1, 2011
Version 3.0 ENERGY STAR Program Requirements for Set-top Boxes became effective on September 1, 2011. The revised requirements include more stringent performance levels as well as incentives for operation in Deep Sleep Mode (less than or equal to 15% of power in On Mode) and use of thin clients in multi-room setups.
What should you know about choosing ENERGY STAR qualified Set-top Boxes?
Most set-top boxes and cable boxes are given to consumers as part of their contract with a service provider, rather than sold independently at retail stores. So, when you are deciding on a cable or satellite service, be sure to ask the service provider for an ENERGY STAR qualified set-top box.
If you currently have cable or satellite service, check with your service provider to find out what, if any, upgrade options are available. ENERGY STAR Partners who provide cable and satellite services may be able to provide newly qualified boxes as part of your service.
